PPS多少钱一公斤？行情走势，耐高温料的价格逻辑
PPS多少钱一公斤？
这个问题一搜，从十八块一公斤到八十块一公斤，报价差得比耐温等级还多。有人说我买的二十二块的改性PPS用得挺好，有人说我买的八十块的雪佛龙菲利普XE5030才叫高性能。到底差在哪？
说实话，问PPS多少钱一公斤的人，大概率还没搞懂PPS这东西不是一个料——纯树脂、玻纤增强、矿物填充、碳纤增强，每个分支价格都不一样。你拿纯树脂的价和碳纤增强比，那不叫比价，叫被忽悠。
一、主流牌号报价（外企+中企）
先把市面上走量的牌号和参考价摆出来。以下为近期市场参考价，实时价格以当日询价为准。
雪佛龙菲利普（Chevron Phillips）
BR-42B，40%玻纤增强，参考价约35-45元/公斤。Ryton系列，高强度、耐高温，汽车电子电气部件。
R-7，40%玻纤增强，参考价约30-40元/公斤。耐磨阻燃，工业部件。
XE5030，玻纤增强高流动，参考价约80元/公斤。高抗冲、热稳定，高端汽车部件。
宝理（Polyplastics）
1140L4，40%玻纤增强，参考价约30-35元/公斤。DURAFIDE系列，线性PPS，尺寸稳定，电子连接器。
6165A7，60%玻璃矿物填充，参考价约30-38元/公斤。耐热阻燃，汽车部件。
东丽（Toray）
A504，纯树脂/低填充，参考价约33-35元/公斤。Torelina系列，耐高温，电子电气。
A305M，矿物填充，参考价约25-30元/公斤。尺寸稳定，精密部件。
新和成（中企大厂）
新和成PPS纯树脂，参考价约18-25元/公斤。国产主力，性价比高，改性基料。
新和成玻纤增强PPS，参考价约22-30元/公斤。增强级，汽车、电子部件。
一句话总结：纯树脂18-25块，玻纤增强25-40块，矿物填充25-35块，碳纤/特殊级40-80块。你要的是啥填充和耐温，决定了你该在哪一档选。
二、同是PPS，价差凭什么这么大
PPS的价格差，主要藏在四个地方。
第一，填充类型不同。纯树脂便宜，玻纤增强贵一点，矿物填充适中，碳纤增强最贵。填充决定了强度、耐温、价格。
第二，分子量和线性度不同。线性PPS比交联PPS贵，分子量高的比低的贵。线性PPS韧性好、加工窗口宽。
第三，功能改性不同。阻燃、耐磨、导电、耐水解——这些都要加钱。你买的不是纯PPS，是加了料的PPS方案。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但质量参差。同样是玻纤增强，雪佛龙菲利普比新和成贵50-100%，贵的是品控和研发。
三、采购避坑：别让耐温等级骗了你
我见过太多采购，比价比到最后选了最便宜的十八块的，然后做出来的制品耐温不够、强度不行、客户退货，一次损失够买半年的好料。
PPS采购这行，水比你想的深。三个坑必须绕开：
第一，看灰分和热变形温度不看牌号。同一个牌号不同批次填充量可能波动，拿到料先测灰分和HDT，和COA对得上再用。别听销售说"差不多"，差不多就是差很多。
第二，警惕以次充好。有些贸易商拿交联PPS当线性PPS卖，拿纯树脂当增强级卖。要COA、要物性报告、要原厂包装，三证合一才敢用。
第三，别只比单价，算综合成本。A料单价18块，做出来次品率5%；B料单价30块，次品率1%。算到每件制品上，B料反而更便宜。
四、标准牌号满足不了？看看改性方案
如果你发现标准牌号怎么选都差点意思——比如要阻燃又要高流动、要增强又要增韧、要导电又要低成本——那不是PPS的问题，是你需要的不是标准PPS，是改性PPS。
这时候可以看看宁波科隆新材目前在做的高性能改性PPS方案，玻纤增强、矿物填充、耐磨、导电这些方向都有对应牌号在做。有特殊需求的可以私信要一份改性PPS的报价参考，比自己买基料再加助剂调试，省的不只是钱，还有试错的时间。
说白了，标准料是大锅饭，改性料是定制菜。你的制品要求越高，越需要定制。
五、常用牌号，私信给你当日报价
上面的价格都是参考价，PPS行情一天一个样，原油、对二氯苯、硫化钠、汇率都在动。
如果你需要雪佛龙菲利普、宝理、东丽、新和成这些品牌的具体牌号当日报价，私信我，发你一份实时价格表。不绕弯子，报实数。
写在最后
买PPS这事儿，十八的和八十的，差的不是六十二。
单价是门槛，选对填充类型和耐温等级才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出合格制品的方案。把账算到每件制品上，再加上次品退货损失，你才知道谁真便宜谁真贵。

How much is PPS per kilogram?
PPS is not one material: different grades, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
PPS
BR-42B, approx. CNY 35-45/kg. high-strength; high-temperature.
R-7, approx. CNY 30-40/kg. wear-resistant flame-retardant; industrial parts.
XE5030, approx. CNY 80/kg. high impact; heat-stabilized.
Polyplastics
1140L4, approx. CNY 30-35/kg. dimensional stability; electronics connectors.
6165A7, approx. CNY 30-38/kg. heat-resistant flame-retardant; automotive parts.
Toray
A504, approx. CNY 33-35/kg. high-temperature.
A305M, approx. CNY 25-30/kg. dimensional stability; precision parts.
PPS
approx. CNY 18-25/kg.
approx. CNY 22-30/kg. reinforced; automotive; electronic components.
2. Why prices differ so much
Four factors: (1) fillers type — lower levels are cheaper; higher levels give better performance but cost more. (2) grade level — premium grades need special formulations and cost more. (3) functional modification — special applications need special formulations or certification and cost more. (4) Brand and origin — imports carry a premium but offer batch stability; for the same grade, imports cost 30-50% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on performance and triggers customer returns. Three traps to avoid:
First, test key properties against the COA instead of trusting the grade name — performance of the same grade can fluctuate between batches. Second, watch out for substitution fraud: some traders pass off cheaper or recycled material as the real thing; demand the COA, a test report and original packaging before use. Third, don't compare unit price alone — calculate total cost per finished part, including rejected-goods loss; a higher-priced grade with a 1% defect rate is often cheaper than a low-priced one with 5% rejects.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — for example you need flame retardancy AND high transparency, reinforcement AND chemical resistance, or low cost AND food grade — you don't need standard PPS, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PPS solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PPS quote reference — it saves not only money but also trial-and-error time.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order. The higher your requirements, the more you need customization.
5. Popular grades — same-day quotes via message
All prices above are references; PPS prices change daily as feedstocks and exchange rates move. If you need same-day quotes for specific grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
Unit price is the threshold; choosing the right grade and performance is the baseline. Do the math per finished part, add rejected-goods loss, and you will know who is truly cheap and who is truly expensive.
